To all whom it may concern:

Be it known that I, SAMUEL H. HAMER, a citizen of the United States, and a resident of Belliiigham, in the county of W'hatconi and State of Washington, have invented certain new and useful Improvements in Receiver Attachments for Telephones, of which the following is aspecification.

The "present. invention relates to telephony, and has particular reference to an attachment for telephone stands for supporting the receiver in proper position from the stand. a

An object of the present invention is to provide an attachment of this character which, when used, admits of the free use of both'hands for writing and other purposes, while carrying on a conversation on the telephone.

. Another object of the present invention is to provide a relatively simply constructed attachment comprising. but few parts, and which may be readily applied-t telephone stands of ordinary construction, without alteration or change in the construction of the stand. I

The above, and various other objects and advantages of this invention will 'he in part described, and in part understood, from the following detailed description of the present preferred embodiment, the same being illusin i the accompanylng draw ngs,

trated wherein? V p Figure 1 is a side elevation of an ordinary telephone stand,having the attachment "of this invention applied thereto, the dotted lines disclosing the attachinent'in' raised operative position.

. Referring to these drawings, wherein like parts are designated by similar characters of reference throughout the several views, A designates a telephone stand of theusual type, provided with a. receiver hook or telephone circuit making and breaking lever PIOJGCtlHg from one side thereof, and hava keyway, as shown in Fig. 3. The shank D of the. transmitter C is fitted in the usual manner betweenthe fork arms 10 and 11, and is suitably apertured for the reception of a pivot pin 12. The pivot pin 12 extends through the fork arm 11, theshank and into the opening inthe fork arin 10,'but is relatively short and does not ext id entirely through the latter. A rela- V tive ly sniall screw 12 extends through the,

fork arm 10 and into the inner threaded end of the pivot pin 12. The pivot pin 12 is held frointurning'in the fork arrn 1.1 by the provision of a laterally extending feather or key 13 engaging in the keyway in the fork arm, 11, and a locking Washer lat is fitted over the pin :12, against the outer'side of the forkarm 11. As shown to advantage in Figs. 3 ands, the locking washer 14 is provided with anouter serrated or toothed surface, and has a keyway communicatingcwith one side of the central,

opening therethrough for the reception of a feather or key 15 projecting from the pin -12 for holding the washer 14 from turning upon the pin. The key 15 is preferablyai ranged at an angle from the key 13, and is adapted to abut against the outer face of the fork arm 11 to hold the pin12' in place. Q

A supporting arm 16' is provided with a" which is apertured, and which is adapted roundedfflat head 17 upon its inner end for engagement over the pin 12. The head 17 has an inner serrated or toothed surface adapted to mesh with the, serrations or teeth of the locking Washer 1 1, for holding the arm 16 in adjusted position when swung about the pin 12.

A spring washer 18 is fitted over the pin llagainst the'outer side of the head 17,

as shown in Fig. 1. arm' 16 is offset outwardly from the base and is held under tension thcreagainst by a binding nut 19, he bindingnut 19 is provided with a'pcripheral milled or serrated surface adapted to receive the fingers thereagainst for turning the nut 19 to ten-.

sion the spring 18.

' The inner form to provide cam surface 20 for sliding e .gageinent over the upper edge of'rthe re-- ceiver hook B for-the purpose of depressing the latter'when the arm 16 is swung down The free end of the portion of the stand A, and is provided with a longitudinal slot 21 adapted to receive therethrougli a threaded stem 22 projecting fronithe rear side of a relativelyflat receiver. E, a binding nut 23 being placed upon the stem 22 and engaging against the outer side of the arm 16, to secure the receiver in lon itudinally adjusted posi-' tion upon the arm. Thearm 16 is provided at suitably spaced-apartpoints with aper- 'tured lugs or loops 24ladapted to receive therethrough the cord or cable F of the telephone for carrying the same to the receiver E.

In Figs. 6 and 7, a slightly modified form ofthe attachment is shown, and which is in Q the form of an attachment to be applied'to the arm 16. a The same comprises a bracket 25. The bracket 25 may be in the form of sheet metal blank comprising. an elongated body bar having laterally'extending straps 26 and 27 upon the opposite ends thereof adapted for engagement about the oppositeends Of a relatively long receiver, such as is now commonly employed. The ends'of the straps :26 and; 27 are turned outwardly to form cars 28, as shown in Fig; 7, and through which pass clamping bolts 29 for binding the-straps 26 and 27 upon the receiver to support the same. One'end of the bracket '25, preferably the end with the'larger loop 26, has an outturned ed for engagement against the side 10f the arm 16, and through which'inay'be bassed a clamping bolt 31. When this: modified attaching lug 30 adaptro n- 0f attachment is employed, the loop 26 is" preferably made of suhicient size to 'renga-ge-against-the outer end of the receiver G and-the loop 27 is relatively small 'to engage about the inner portion thereof.

- The operation of the deviceis apparent,

f for when the telephone is to be used, the

' arm 16 may be swung intothe dotted-line position shownin'. Land the nut 19 is i tensioned against the spring'lS sufficiently to bind the arm 16 in raised position for supportingthe receiver. 'As'the' free end of the-arm 16 is ofl'setoutwardly from the standard A,'the receiver-E, or G, is supported in proper: position against the, ear whilethe'. mouth is directly opposite the end of the arm 16, which emerges from the head 17, is arcuate ii'i' and being restricted only transmitter G. \Vhen the telephone stand A is placed upon a desk, table, or the like, both hands of the person using the telephone, are free to take notes or to perform other such functions. When it is necessary to support the telephone in the hand, but one hand is necessary to hold the standard A.

1V hen the arm 16 is swung down into an out of the way position, the cam surface 20 thereof engages the receiver hook B, and

depresses the same for cutting out the telestand, and an arm pivotally mounted upon said pivot pin and supporting the receiver,

said arm mounted to swing independently of the transmitter- 2. The combination with ,a telephone stand, transmitter and receiver, of a pin pivotally supporting said transmitter on said stand, an armpivotally mounted upon the pivot pin ofsaid transmitter, means for connecting said receiver to said arm to permit adjustment of the receiver longitudinally onthe arm, said arm moiuited to swing independently of the transmitter.

3. The combination with a' telephone stand having an apertured portion at its upper end, a pin fitting in thejapertured portion, means for holding the pin from turning, a locking washer keyed upon the 1 pin and having an outer serrated surface, a

supporting arm pivotally mounted on the pin and-having a serrated surface adapted to engage the serrated surface of the washer, a spring,washermounted upon said. pin, a binding nutmounted upon the outer end of the pinfand adapted for engagement against the spring washer to tension the same, and means: on the outer end of the'arm for engaging a telephone receiver.

, 4..In an'attachment as specified, the combination with a telephone stand having a transmitter on the upper end thereof and a receiver,,of a pinprojecting from the upper end of the stand, an arm 'hingedly mounted on the pin, a spring washer mounted upon said pin,;m"eans, for Itensioning said spring washer for retainingthe arm in various ad- 5 juste'd positions 'upon the pin, and'means for adjustablylholding a receiver upon the outer end of-the arm;

5; In a telephone attachment, the oomhi nation of a telephone stand having a transmitter on its upper end, and a hook project ing from the side of the stand, and a receiver,eof an arm pivotally mounted upon the upper end oi the telephone stand and adapted to support the recelver, said arm shaped to form a cam portion thereon for en 'a 'in said receiver, hook for retainin b b b i b the same in depressed position when the arm is swung down.
